Title: Improvements in and relating to change-box mechanisms for looms, in which the shuttles are changed at one or at both ends
IPC: D03D43/00
Filed: 1923-07-27
Abstract: 201,911. Maschinenfabrik R³ti vorm. C. Honegger. Aug. 4, 1922, [Convention date] . Change-box motions for operating at one or both ends of the lay and of the kind in which driving-pins on a continuously rotating wheel act on toothed segments controlling a lever connected to the change-box, and in which the pinion is brought to rest after every partial revolution by parts on the segments striking against a rim on the pin-wheel, are provided with means on the pin-wheel and on each toothed segment for ensuring smooth positive engagement and disengagement of the segment, and positive stopping thereof without shock at every partial revolution of the segment. The invention may be applied to looms having more than two shuttles. As shown, the pin-wheel 2, Figs. 3 and 7, is provided on each side with fixed pins 3, 4, longer spring-controlled pins 5, 6, cylindrical parts 9 - - 12, and cut-away portions 13, 14 leaving narrow strips 9<1>. The parts 11, 12 are shorter axially than the parts 9, 10. The pinion 15 which is moved axially under the control of a dobby, jacquard, or other loom pattern mechanism, is mounted on a bush 18 loose on a fixed shaft and is provided with two toothed segments 16, 17. Each segment has oppositely disposed portions 25, 26 for resting on the cylindrical parts of the pin-wheel, the part 26 having a cranked or offset portion 26<1> adapted when operative to rest on the cylindrical strips 9<1>, and an inclined guide 31 through which the longer pins 5 and 6 can pass. With the parts in the position shown, the leading pin 3 engages a curved part 27 on the toothed segment 16, and further rotation causes the segment to complete half a revolution, the pin 5 disengaging from the segment on a curved part 28 and bringing the pinion to rest in a positive manner. If no change of pattern is indicated, the pins 5, 6 are moved back against the action of their springs and engage the inclined guide 31 of the offset position, which is out of the path of the fixed pins 3, 4. When the pattern is to be changed, the pinion is moved axially, and the other toothed segment is moved into engagement with the pins 3 or 4 on the other face of the pinion, which is thereby rotated and operates the shuttle-box 24 through a connecting-rod 21, lever 22, and link 23.

Abstract: 692,292. Generating combustion products under pressure. JET-HEET, Inc. Aug. 16, 1951, No. 19344/51. Class 51(i) [Also in Group XI] A liquid or gaseous fuel burner, which is mounted within a casing (not shown) supplied with air under pressure, comprises spaced coaxial shells 16, 18 to the annular space between which air under pressure is supplied, and fuel, e.g., liquid fuel sprayed by a return flow type injector 10, introduced into the inner shell 16, which has comparatively large holes 34 for the passage of sufficient air for substantially complete combustion and which is provided throughout most of its area with closely spaced perforations 30, 32, 35, through which air seeps to provide a layer of air as the inner wall of the shell 16 for preventing carbonaceous deposits thereon. The perforations 30 in the part, approximately one-third of the shell 16, nearest the fuel injector 10 are more widely spaced than the perforations 32, 35 whereby the base of the flame is improved, or, alternatively, the perforations 30 may have the same spacing as the perforations 32 but a smaller effective area, as by forming the said third portion of the shell 16 with a double layer of sheet metal perforated in the same manner as the single layer forming the remainder of the shell. A baffle 36 impedes the flow of air through the perforations 35 disposed near the outlet of the shell 16, whereby said air is heated and seeps less freely to improve the flame. Air enters the annular space between the shells 16, 18 at the flame outlet end, the shell 16 being cylindrical and the shell 18 being slightly tapering, and the opposite end of the annular space is closed by a plate 20 secured to the shells 16, 18 by cotter pins 24. In a modified construction the annular air supply chamber is open at the fuel inlet end of the burner and closed at the opposite end.

Abstract: 680,864. Windscreen cleaners. LUCAS, Ltd., J. July 26, 1951 [Aug. 3, 1950], No. 19390/50. Class 138 (i). A coupling for attaching the wiper blade q, Fig. 1, to the oscillation arm d of a vehicle windscreen wiper comprises a hollow knob of substantially rectangular form and adapted to be placed over the outer end of the arm d, a claw e on the knob adapted to engage a hole f in the arm, a substantially tee-shaped trunnion having its head g enclosed by the knob and its stem h extending through a hole in one side b of the knob, the outer end of the stem h being adapted for attachment thereto of the blade holder p, and a spring k for retaining the claw e in engagement with the arm d and for pressing the head g against the side b, which side has therein a concave surface (formed by a recess i) on which rounded surfaces j on the head g can rock. The knob is made from two metal parts a, b, the part a being of box-like form while the part or side b encloses the open side of the part a and is secured thereto in any convenient manner. The knob has an apertured recess c to receive the end of the arm d. The hole f in the arm is rectangular in cross-section. Preferably interposed between the blade spring k and the head g is a shim m and the head is formed with a longitudinal ridge of shallow vee-form to engage with the shim. The head g is preferably shaped to a diamond form as shown in Fig. 2 so that the extent of angular movement of the head is limited by contact of its ends with the inner side walls of the knob part a. A screw or rivet o secures the stem h to the holder p. The head g can thus rock relatively to the knob about two axes which are mutually at right angles, one axis being that of the stem h and the other axis coincides with the base of the recess i. When the blade twists relative to the arm about the axis of the stem h e.g. when parking the blade, the parts j of the head g ride up the sides of the recess i against the spring k. The parts also return to their normal positions under the action of the spring k. The blade can also rock about the longitudinal axis of the recess i so as to assume alternate inclined positions en the windscreen each time the blade reaches the end of its oscillatory movement.

Abstract: 753,452. Colour television tubes. PHILCO CORPORATION. Aug. 1, 1952 [Sept. 14, 1951], No. 19512/52. Class 39 (1). The screen described in Specification 753,449, [Group XX], comprising a combination of fluorescent strips and indexing strips, is modified by mixing the indexing material with the material of some of the fluorescent strips, preferably those responsive to beam impingement in the same primary colour. The screen comprises glass support 32, Fig. 2, carrying a thin transparent conductive film 33 of stannic oxide and, over the film 33, fluorescent strips 34, 35, 36. A material or materials of different secondary emissive ratio from the red and blue strips may be mixed with the green strips. The added material or materials are such as not to affect the phosphor chemically to impair the brightness or colouration of its light emission, and are preferably mixed with the phosphor before deposition. They may be mixed with the phosphor or phosphors whose light emission efficiency is greatest so as to achieve colour balance. The added material may be uniformly or non-uniformly distributed, and in the latter case may be of higher concentration near the surface exposed to the beam. Since the secondary emissivities of the phosphors are different, green usually having the lowest value, more additional material will be required if it is desired to mix it with the green than with the other phosphors to produce the same differences in the collected output. The green, blue and red phosphors may be zinc orthosilicate, calcium magnesium silicate and zinc phosphate respectively, and the indexing material may be magnesium oxide, gold or tungsten. In an example the green phosphor contains 25-75 per cent by weight of magnesium oxide. The phosphors may be deposited by silk screening, settling or spraying, preferably the latter. The screen base may be sprayed over its whole surface successively with the different phosphor materials, one of which is mixed with magnesium oxide, and the vehicle being polyvinyl acetate and ammonium dichromate. When a single layer has been deposited it is exposed to light through narrow slits in a mask, the irradiated portions thus being fixed and the remaining portions then washed off. The mask is moved or a different mask used for each set of strips. Specifications 753,448, [Group XXXV], and 753,551, [Group XL (b)], also are referred to. Reference has been directed by the Comptroller to Specification 669,848.

Abstract: Zircon-containing material which has previously been purified, say to a residual content of 0,20 per cent titanium oxide and 0,10 per cent ferric oxide, is treated with a halogen in the absence of air and in the presence of not more than 1 per cent carbon at say 950 DEG  C. to form and volatilize halides of the remaining impurities.  Chlorine is the preferred halogen, but bromine or iodine may also be used. Preferably, the initial material, which may be the product obtained by the process described in Specification 444,285, is finely milled and formed into nodules after being mixed with carbon and a binder. As carbon, lamp black, graphite, petroleum coke, or soft coal may be used, and as binders, gum tragacanth, dextrine, sugar, or glue. The carbon requirement may also be supplied by using sufficient of the carbonaceous binding agent, or by using gases such as carbonyl chloride or a mixture of carbon monoxide and chlorine.  In examples using chlorine or bromine as the halogen 0,2--0,3 per cent lamp black and 0,05--0,10 per cent gum tragacanth are generally used, but in one example a less finely milled initial material is treated in powder form with addition of lamp black.
